David Suchet teases 'lonely' Poirot

Poirot star David Suchet has revealed that the lonely nature of the Belgian detective will be explored in future episodes.

However, he told Hollywood Today that the character's personality remains more or less constant.

“Apart from the fact that I’m getting older, which I can’t help, Poirot doesn’t change much, just as the man that [Agatha] Christie wrote about hardly changes," he explained. "He does get lonelier as he gets older, which we are beginning to bring out in the films.”

The actor also praised the improved production values of the adaptations, noting that newer episodes are "all very high-quality productions" in comparison to the more modest early episodes.

The latest Poirot film - a new adaptation of Murder on the Orient Express - was broadcast on July 11 on American network PBS. Suchet revealed that he enjoyed playing a more three-dimensional version of the character than has been seen in previous adaptations.

“In books like Murder on the Orient Express, there are sections that point to a very perturbed inner life,” he said. “This side of him was totally ignored in the 1974 Sidney Lumet film [version].”

Suchet's Murder on the Orient Express has not yet been broadcast in the UK.
